Kaspa is a POW public chain built on the GHOSTDAG protocol. Compared to Bitcoin, Kaspa mainly changes the structure pattern of the blockchain. Bitcoin adopts a single chain structure, while GHOSTDAG adopts a directed acyclic graph (DAG) structure, where one block can point to multiple blocks.
The token KAS was launched in November 2021, with a total supply of 28.7 billion and a circulating supply of 19.8 billion, accounting for 69% of the circulation. Its market value is 750 million USD with a FDV of 1.08 billion USD. Since the token was launched, its value has increased by hundreds of times.


1. Team

II. Technical Principles
The technical principles of Kaspa are mainly discussed in its 2021 paper "PHANTOM GHOSTDAG: A Scalable Generalization of Nakamoto Consensus".
Bitcoin is essentially an open and anonymous node network that maintains a public transaction ledger. The ledger adopts the "longest chain" principle to connect honest blocks to each other and protect the security of the network. This design artificially restricts the throughput of the network, resulting in low protocol scalability. Currently, the Bitcoin network produces one block every 10 minutes, with a transaction throughput of 3-7 transactions per second.
Structural Model: Directed Acyclic Graph (DAG) Structure
Kaspa proposed the PHANTOM protocol, which is a permissionless ledger protocol based on proof-of-work, and extends the blockchain defined by Satoshi Nakamoto to a directed acyclic graph (blockDAG). PHANTOM can reference multiple previous blocks, provides a total ordering of all blocks and transactions, and outputs a set of consistent and accepted transactions.
PHANTOM includes a parameter k, which controls the protocol's tolerance for concurrently created blocks, and can be set to accommodate higher throughput. When k=0, it means no forks, similar to Bitcoin's single chain, longest chain structure.

Let's first understand several different types of blocks in DAG. The corresponding concepts will be used in the examples below. In the figure above, take block H as an example:
past(H)={Genesis, C, D, E} — — the past blocks that directly or indirectly point to block H before its creation;
future(H)={J, K, M} — — the future blocks that directly or indirectly point to block H after its creation;
anticone(H)={B, F, G} — — the blocks that are not in the future of block H;
I, L} - Blocks other than the past(H) and future(H) have no direct or indirect relationship with H;
tips(G)={J, L, M} - Leaf or terminal blocks, these blocks will be referenced by the block header of the new block.
Identifying honest blocks and malicious blocks
PHANTOM solves the problem of identifying honest blocks and malicious blocks. Malicious attacks have one characteristic: the connectivity between blocks generated by malicious nodes and blocks generated by honest nodes is low, while the connectivity between blocks generated by honest nodes is high.
The criterion for judgment is the parameter K value mentioned above. For a specific block X, if the intersection of anticone(X) and honest blocks is higher than the k value, it means that the connectivity between block X and honest blocks is low, and X will be judged as an attack block; otherwise, it indicates that the connectivity between X and honest blocks is high, and X is considered an honest block.
The following figure shows the honest blocks and attack blocks.
Judge. The value of K here is 3. After inspection, the blue part is the honest block, and the red part is the attacking block.

Linear Sorting
To resolve the double-spending problem, the project team applied the GHOSTDAG protocol. The principle is to score each block based on its connectivity (the number of elements in the past block set) and choose the block with the highest total score to form the main chain, which forms an initial subset. The remaining blocks will vote in the order of the main chain. The entire network will vote in a trend from high to low connectivity.
The following image shows how GHOSTDAG completes the sorting process with parameter K=3. The small circles on each block X represent its score, which is the number of blue blocks in the past DAG.
In Step 1, starting from the block M with the highest score, select blocks K, ...
,  and Genesis block, are marked with blue background and black border, forming the initial subset. Access block , the past blocks of D only have Genesis block.Step 2, access block , the past blocks of H include C, D, E. After identifying honest blocks and attack blocks according to the aforementioned method, C, D, E are considered honest blocks and added to the subset, marked with blue border. 
Step 3, access block , the past blocks of K include H, I. After identification, both H and I are considered honest blocks, marked with blue border. 
Step 4, access block , the past blocks of M include K, F. K is considered an honest block, added to the subset, marked with blue border. 
Step 5, block  is a virtual block, and its past is the entire current DAG.

3. Mining Power Status
Kaspa mining algorithm is kHeavyHash, which supports GPU solo mining or dual mining with ETHW and ETC, as well as partial FPGA and ASIC mining machines.
According to the official blockchain explorer, Kaspa's mining power is 2.6 - 2.7 PH/s. According to Mining Pool data, Kaspa's mining power ranks around 30th, after BCH, BSV, DASH, and before DOGE, LTC.
Kaspa's mining power shows a continuous growth trend. In October 2022, and December 2022sp;In February, 2023, July 2023, there were four significant increases in computing power. In March of this year, mining equipment manufacturers introduced professional miners to improve mining efficiency for miners.

IV. Token Economic Model
Token Distribution
KAS, launched in November 2021, has no pre-mining, no pre-sale, and no token distribution. The total supply is 28.7 billion coins, with a circulating supply of 19.8 billion coins, accounting for 69% of the total, with a market value of $750 million and a FDV of $1.08 billion.
Token Release
According to the emission plan, KAS reduces its output every month in a given manner, resulting in a halving of the output each year. The following diagram illustrates the token release, showing higher release rates in the early stages, allowing early miners to accumulate a large number of chips. The specific release schedule can be found on the official website (https://kaspa.org/wp-content/uploads/2022/09/KASPA-EMISSION-SCHEDULE.pdf.

According to the token emission table, the monthly emission volume and release value of KAS tokens from July 2023 to June 2024 were calculated as shown in the table below. If calculated at a price of 0.037, in July 2023, KAS will emit tokens worth $19 million, gradually decreasing thereafter; by June 2024, the emission value will be approximately $10 million.

Holdings
There are a total of 26.7 thousand addresses holding 1 or more KAS tokens. The token distribution is also relatively concentrated, with the top 10 addresses holding 17.299% of the tokens, mainly in exchange wallets. The top 100 addresses hold 26.13% and the top 1000 addresses hold 61.35%.
Looking at the token flow, in the past 30 days, addresses holding 100-10K tokens have seen a decrease in holdings, while addresses holding 0-100 tokens and 10K or more tokens have seen an increase. In the past 7 days, addresses holding 100-10K tokens and addresses holding 100M to 1B Humpback tokens have seen a decrease in holdings, while other addresses have seen an increase.

Development Plan
- Implement smart contracts and establish an ecosystem 
Kaspa aims to achieve smart contracts, Defi, and Layer 2 applications on its public chain and build the corresponding ecosystem.
The development and deployment of smart contracts are vital factors for its further development. If smart contracts can be deployed in a timely and smooth manner, and an ecosystem with a certain level of activity can be established, Kaspa's market value still has room for further growth. However, if the deployment of smart contracts encounters difficulties and the ecosystem fails to develop, there will be noticeable bottlenecks in future development.
Summary
The project team has strong technical capabilities and a good development foundation. They have proposed a new blockchain model and explored new development directions. They have also gained mining power transferred from Ethereum in the early stages and have seen a continuous increase in mining power.
The market value is high and has risen more than a hundredfold. Currently, KAS market value is 7.5&nbs;
Billions of dollars, ranking around 60th, the market has already fully valued the technical team and computing power growth. Future growth will require stronger expectations to support it.
There is a potential selling pressure for tokens. Early miners hold a large number of low-priced chips, and there is also continuous daily output. If sold, it will cause significant price impact.
